How is eye snot created?

The scientific term for eye snot is rheum. It is a combination of mucus, oil, and dead skin cells that collects in the corners of the eyes.

Mucus is a substance produced by the mucous membranes, which line many parts of the body, including the eyes. It helps to protect the eyes by trapping dirt, dust, and other foreign objects. Oil is produced by the sebaceous glands, which are also located in the eyelids. It helps to keep the eyes moist and prevents them from drying out. Dead skin cells are constantly being shed from the surface of the skin, including the eyelids. These cells can collect in the corners of the eyes and contribute to the formation of rheum.

Rheum is usually not a cause for concern. It is simply a sign that the eyes are doing their job to protect themselves from the environment. However, if you are producing excessive amounts of rheum or if it is accompanied by other symptoms, such as redness, swelling, or pain, it is important to see an eye doctor.
